Okay, this was weird. I decide to pop in Wii Sports last night and play a game of tennis. When it starts up, I get this "Check your batteries at the home page, cause they are low" thing. And I was like WTF, it's down to one bar?! I had played Wii Sports the night before and I specifically remember checking the status of the batteries, and they were full.
Has anyone else had this sudden drainage? I kinda wanna blame the batteries, cause they are the cheap Maxell ones that came with it, but I dunno.
